This is difficult to describe in text, without sketches, but I'll try:
-- First, the 'equator' of the sky: That's a line all around the sky that's exactly
over the Earth's equator. In your sky, wherever you are, this 'celestial' equator
is a semi-circle from the exactly-east point on your horizon to the exactly-west
point. Its highest point is due south of you, and at that point, its height above
your southern horizon is (90 degrees minus your latitude). If you're on the equator,
then the celestial equator passes right over your head. If you're at the north pole,
then the celestial equator coincides with your horizon. If you're in Minneapolis,
Salem OR, Bangor, Grenoble, Torino, or Belgrade, at 45° north latitude, then it
passes 45° above your south horizon.
-- The highest of the 3 stars in Orion's belt is on the celestial equator.
-- The ecliptic is another line all the way around the sky. It crosses the celestial
equator at two places, and it's tilted 231/2 degrees to the equator. So half of the
ecliptic is above (north) of the equator, and the other half of it is below the sky's
equator.
-- Through the day, as the Earth turns, one of the two points where the ecliptic
crosses the equator will be in your sky at any one time. The ecliptic will appear
high in your sky for half of the day, and low in the sky for the other half. The
point where it crosses directly south of you will wiggle up and down through a
total of 47 degrees in 24 hours.
-- The left pincher of Scorpius and the heart of Leo (Regulus) are on the ecliptic.
The eye of Taurus (Aldeberan) is not too far off of it.
The ecliptic is actually the line where the plane of Earth's orbit cuts through the
'bowl' of the sky. Some of the results are:
-- The sun is always on the ecliptic.
-- The planets are always close to the ecliptic. Now, in mid-2013, Jupiter is smack on it.
-- The moon is always within about 51/2 degrees of the ecliptic.
-- In Summer, the sun is high, so the ecliptic ... with the moon and planets ... is
low during the night.
-- In Winter, the sun is low, so the ecliptic ... with the moon and planets ... is
high during the night.
Remember those two points where the ecliptic crosses the celestial equator ?
Those points in the sky are the 'equinoxes'. Those points are where the sun is
on March 21 and September 21.
What else can I help you with?
What solstice is the point on the ecliptic when the suns declination is mostly southerly?
From the perspective of the Northern Hemisphere, this solstice will be called the "winter" solstice.
If the earth stopped revolving when the northern hemisphere was pointed towards the sun would you have longer nights or days?
All you would have is a day where the Northern Hemisphere was pointed at the sun. The side opposite would be in permanent night. it would have nothing to do with Hemispheres but with which side is pointed to the sun. Alternate: If by 'pointed towards' you mean at the same angle as the current tilt, then the answer would be a little different. But the answer would depend on where you are. Or are you one of the many who assume that the northern hemisphere is the only one? If you are in the northern hemisphere, you would have longer daytime periods than night. It would be opposite in the southern hemisphere.
What is the place where the sun stops its northward motion along the ecliptic?
The place where the sun stops its northward motion along the ecliptic is known as the June solstice or summer solstice. This is when the sun reaches its northernmost point in the sky, marking the beginning of summer in the Northern Hemisphere.
Where is the constellation Leo located in the night sky?
The constellation Leo is located in the northern celestial hemisphere. It can be found between Cancer to the west and Virgo to the east. Leo is visible in the sky during the spring months in the Northern Hemisphere.
What star is the brightest in northern hemisphere?
After the Sun, the brightest star is Sirius, in the constellation Canis Major. However, while Sirius is the brightest star visible from the Northern Hemisphere, it is part of a southern hemisphere constellation. Therefore, Arcturus, in Bootes, would be the brightest Northern Hemisphere star.
Where is constellation Scorpio located?
Gemini is a zodiacal constellation in the northern hemisphere between Taurus and Cancer on the ecliptic.
What solstice is the point on the ecliptic when the suns declination is mostly southerly?
From the perspective of the Northern Hemisphere, this solstice will be called the "winter" solstice.
What hemispheres is kyrgyzstan?
It is in the northern hemisphere and would also be in the eastern hemisphere.
In which hemisphere would you find the strait of Gibraltar?
It's in the northern hemisphere.
What hemisphere is Baghdad in?
if you looking for one hemisphere that it lies on then it would mainly be on the eastern around saudia arabia. but if your looking for to it would be the northern eastern hemisphere
How would the passage of one year be different for someone living in the Southern Hemisphere than in the Northern Hemisphere?
In the Southern Hemisphere the seasons would be the reverse of what the seasons are in the Northern Hemisphere
If the northern hemisphere is experiencing spring what season is it in the southern hemisphere?
It would be autumn in the northern hemisphere.
Which hemisphere would you be in to see the Aurora Borealis?
northern hemisphere
In what hemisphere would you find in Washington DC?
Northern Hemisphere
May 15 gaining or losing time each day?
In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.In the northern hemisphere there would be more daylight each day and in the southern hemisphere there would be less daylight.
What is event symbols the start of summer in the northern hemisphere?
The beginning of astronomical Summer in the nothern hemisphere is the moment when the center of the sun reaches the northernmost extent of the ecliptic in the sky, known as the solstice, on June 21 or 22.
If the earth stopped revolving when the northern hemisphere was pointed towards the sun would you have longer nights or days?
All you would have is a day where the Northern Hemisphere was pointed at the sun. The side opposite would be in permanent night. it would have nothing to do with Hemispheres but with which side is pointed to the sun.
